A first inversion triad, expressed numerically as a 6-3 chord, has its original middle note as its bass, with the original top note a third above it and the original bottom note, the root, a sixth above it. Thus the tonic triad of C major is C-E-G in root position, and E-G-C in first inversion.
三和弦第一转位用数字6-3和弦来表示,以原中间音为低音,原最高音为其上的三音,原最低音,根音,为其上的六音。C大调主音三和弦在原位为C-E-G,第一转位为E-G-C。

There are three copies of R fragment in the S mt-genome, and each copy contains two closely adjacent open reading frames: orf355 and orf77. Among these three copies two BamHI fragments were cloned, and the sequence analysis showed that cox1 and cox2 gene lies upstream of the R region in each fragment, respectively. However, they locate in different strands and head to head with R. In this study, we found that:(1) The expression of cox1 and cox2 is not affected by the transcription of R region;(2) The two copies of R region transcribe in large amount in the microspores, and produce transcripts of 1.6kb and 2.8kb, respectively, in the sterile microspores; However, the abundance of these two transcripts is reduced in the fertility restored microspores, realized through the mRNA decay, and this reduction occurs at the uninucleate microspore stage;(3) In the sterile microspores, the 5 terminus of the 1.6kb transcript contains a palindrome region that can fold into a stem-loop.
本研究发现:(1) cox1和cox2的转录没有受到R区转录的影响;(2)两个拷贝的R区在在不育花粉中高丰度表达,其转录本大小分别为1.6kb和2.8kb;而在育性恢复的花粉中,这两个转录本的丰度被大大降低,进一步分析表明这一结果是通过mRNA分子的降解途径来实现的,此降解过程发生在单核花粉期;(3)在不育花粉中,1.6kb转录本的5′末端具有一段可形成茎环结构的迴文对称序列,而在可育花粉中,其5′末端短缺了9个碱基;(4)在不育花粉和育性恢复的花粉中,R区转录本的加尾位点都集中位于一个3′茎环结构之后;(5)不管是在不育花粉还是育性恢复的花粉中,orf77区域内均在第52位和100位核苷酸处发生了不同频率的C向U的编辑,从而形成UGA终止密码;(6)不管是orf55-orf77的成熟转录本还是转录前体分子,都已被加上了Poly尾巴,表明已进入降解途径;在以上实验结果的基础上,本研究对S型CMS花粉育性的恢复机理进行了如下推测:在不育花粉和育性恢复的花粉中,orf77区域内均发生了终止编辑,即由RNA编辑产生了提前终止密码子。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
